You can, but it's a wedge to get it there, and then you've got to hassle with putting everything else on another drive.
It's a netbook, so IMHO the SSD
is more for stability than for performance (performance being limited by the atom processor and the limited RAM).
I was at the same decision you are at and I went for the bigger standard, platter drive. Oh, so much cheaper, and oh, so much more room (even the 120gb will seem palatial compared to the 8). In the states, the 120gb is the el cheapo configuration, so that should save you some moola if it's available there.
